What's up guys. Recently bought an 1991 s13 with a ka24de. Car ran great for about a month but recently its been giving me a few problems. Once in a while it will start and then immediately die about 5 seconds later. Each time I try to start it after this the car sounds like it gets less and less fuel until it wont fire at all, just cranks. I just replaced spark plugs so I'm assuming this is either the injectors or fuel pump?

Another problem is with the idle. When the car does start, it will idle around 1100-1200 (when cold) and then the warmer it gets the lower it idles. Eventually it will idle around 600-650, when it's fully warm. I'm guessing this is due to the MAF, Idle air control valve, or the injectors.

If anyone has any info on how to get this thing running solid again that would be great. Thanks
